Application filed October 27, 1921.- Serial No. 510,961.

the borough of Brooklyn and State of New" York, have invented certainnew and useful Improvements in Window Guards. of which the following isa specification.

This invention relates to a window guard of the kind employed to preventpersons from falling through a window.

The primary object of the invention is to place within the easementoutside the lower sash a guard that can be readilv ad usted vention, 1is the casement, 2 the sash guides,

to position and removed therefrom at will.

Another object of the invention is to construct the several parts insuch manner that they can be quickly assembled in position withoutcutting or marr'ing the woodwork or attaching any part thereof to thecase ment.

Another object of the invention is to construct the guard in such mannerthat when the same is adjusted to assembled position it will besufficiently strong to insure safety under all ordinary conditions.

Another object of the invention is to have the supporting casementstrips, the guard rods and the binding nuts thereon so constructed andarranged that the entire guard can be quickly assembled anddisassembled.

Other and further objects, including certain features of constructionwill appear in the specification and be pointed out in the appendedclaims, reference being had to the accompanying drawings which show thepreferred embodiment of my invention.

In the accompanying drawings:

Figure 1 is a front elevation of a window casement showing the guard asplaced in position.

Figure 2 is a transverse vertical section of Figure 1.

Figure 3 is a detail perspective view of a portion of the member whichfits into the casement and receives the guard rods.

Figure 4 is an enlarged detail showing the guard rod, the nut and howsaid nut en gages a casement strip.

Figure 5 is an enlarged detail sectional .view of the nut and guard rod.

Figure 6 is a modified form of the nut. In the preferred embodiment ofmy in- 3 the lower sash, 4 the upper sash and 5 the window sill ofawindow of standardiacon struction. I

Fitted within the lower portion of the guideway 4. of the upper sash andwithin the casementaretwo w oo-den' strips'ior members 6. Thesestripsare preferablyma de'fof suflicient thickness to projectsomewhat-in ward beyond the sash strips" 2. 'illie lower ends of thesestrips rest on the windowvsil'l while the upper end terminates alshortdis: tance below the bottom of the upper sash.

These strips have therethroughcholesi', said holes being preferably fourin number and equally spaced from the top to the bottom of said strips.

The guard rods 8 are suitably threaded on their ends, as shown at 9, toreceiyethe binding nuts 10. These nuts are intern .ll-y threaded asshown at 11 to receive the rods 8 and also have on their ends heads 12which fit into the holes 7 in the strip 6. The body of each nut 10 isshouldered as shown at 13 for the purpose of engaging the strip 6 andforcing said strip into posi tion in the easement at the same timetightening the rods between the two nuts. In

order to readily turn these nuts into position, a portion of the surfaceshown at 15, has been knurled.

The manner of assembling a guard with:

in a window, assuming the lower sash to be raised as shown in Figure 2,is as follows. The strips 66 are placed within the lower portion of theupper sash guideways a" so that the bottoms of the same rest on thewindow sill. Each rod 8. which has been previously screwed within itsnuts to the limit is held in horizontal position so that the head ofeach nut is adjacent a hole 7 in strip 6. The nuts are then screwedoutwardly on the rod permitting the heads 12 to enter said holes 7 instrips 6. When the nuts are screwed outwardly on the rod a definitedistance, the shoulders 13 of said nuts will en age the strips aroundthe holes therein and rorce said strips tightly against the casement, atthe same time holdingsaid of same, as

rod rigidly between the strips. The same operation of engaging the rodsthrough the medium of the nuts is continued until all of said. rods arein the position shown'in Figure 1. i r

It should be understood that when the nuts are screwed inward ontherods, as

' of said rod and nuts will be less than the distance between the stripswhen said strips are in position in the easement.

While these rods are made strong enough to resist ordinary pressurebrought against them in case of accident, they can be readily removed incase of fire or emergency by seizing the rod in the middle and pullingsame so that it will be buckled andthen quickly removed from engagementwith the strips. 1

It will be observed that the guard, after being secured to the easementwill in no manner interfere with the movement of the lower sash in viewof the factthat the said guard is placed within the lower portion of theguideway of the, upper sash.

In Figure 6, a modification is shown wherein the nut 20 has a threadedopening 21 extending entirely therethrough. This nut has a head portion22 which fits within a, hole 7 of strip 6 and is also provided with ashoulder 23 which abuts the strip to firmly hold the rod in place whenthe nut is tightly adjusted against said strip. Instead of using aknurled nut as shown in Figure 4, a win nut 25 is employed for adjustingsaid ro to proper position. The

when

rods are of a length to permit them,

to be the nut is screwed fully back thereon, placed between the strips6.

Of course, it should be understood that changes can be made in theconstruction and application of this guard without departing from thespirit of the invention.

A guard for windows, comprising members having holes therein and adaptedto fit within the sash guideways of the casement, guard rods-shorterthan the distance between said members when said members are within thesash guideways, flanged nuts on the ends of said rods capable of beingscrewed onto said rods so that the distance between the outer ends ofthe heads of said nuts on the rods will be shorter than the istancebetween the members when said members are in position in the easement,and portions on the outer end of said nuts adapted to fit within theholes in said members when the nuts are screwed outward on said guardrods permitting the flanges on said nuts to engage the members and holdsaid rods and members firmly in desired position.
